I follow a lot of new anime every season (almost all), and I have to say it's hard to pick a favorite this season. Free!, Gatchaman Crowds, Gin no Saji, and Highschool DxD New are in a tie in being my number 1 favorite. Free! is perfect in almost every aspect, as expected from KyoAni. I'm not familiar with the Gatchaman franchise before, but Gatchaman Crowds has a really unique art style and I like it very much. Story's pace is taking it easy, and the characters are really lovable (Hajime is a cutie!). Gin no Saji is a nice relaxing anime to watch, sometimes it makes you laugh and one thing that I like is that it's a high school anime that doesn't have much romance (yet?) and the story focuses on Hachiken's harsh but hilarious school life in an agriculture school. Highschool DxD New (and the previous season) is probably the best harem series I've ever watched. Honestly, I picked up this series a few months ago because my bias Yuki Kaji is on the cast list as the main character, and it didn't disappoint me to the tiniest bit. They clearly used their budget on the animation pretty damn right, the story has some actual sense and not just blatant fanservice every single minute, and all characters have interesting image and later development (except Kiba but not until season 2).
Dangan Ronpa The Animation is also really good, I can't understand why people dropped it because of the pink blood censoring, or I think it's because I've been a fan of the DR franchise since the anime hasn't announced. I mostly read the LP, but I've played the game a bit, and I like how they animated the school trial, and the execution scenes. Only, I kind of don't like how they made their eyes sparkly in the anime.
